The selection butt 1C engages with the tack cam 6 of the outer race, and the third selection butt 2C engages with the tack cam 6 of the inner race. As a result, the knitted fabric including the tack as shown in FIG. 6B may be knitted by several turns on the knitted fabric end of each interlock knitted fabric or the saturated knitted fabric end as shown in FIG. 6A. Get down. When the knitted fabric is taken out, by cutting at the knitted fabric portion including the tack, the knitted fabric can be prevented from unraveling. In addition, when a knitted fabric that is difficult to unravel is originally knitted, a knitted fabric including a tack is knitted instead of inserting a color thread, and the knitted fabric serves as a mark.

Hereinafter, a signal transmission path and a series of operations of the control method in the needle selecting means driving means of the present invention will be described with reference to a block diagram shown in FIG.

First, the knitting machine count meter section 20 has a first preset value that defines the number of rotations of the knitting machine starting from “0” and reaching the saturated knitting fabric production count after which rotation. Is set. In addition to the saturated production amount of the knitted fabric, a second preset value is set at the other end of the knitted fabric, which defines how many turns of the knitted fabric including a tack for suppressing the knitting of the knitted fabric are lowered. Also, a third preset value is set which defines how many knits of the knitted fabric (the same knitted fabric or another knitted fabric) should be knitted down to the cutting position (the position where the knitted fabric is taken out) in addition to the knitted fabric including the tack. Is done. In addition, a fourth preset value is set which defines how many revolutions a knitted fabric including a tack is added and knitted down every time one reverse knitting is performed.

When the knitting machine reaches the first preset value of the saturated knitted fabric production amount, a low-speed signal is sent from the knitting machine count meter unit 20 to the power motor control unit (inverter) 21.
And the knitting machine is operated at low speed. On the other hand, the knitting machine count meter unit 20 outputs an excitation signal to the needle selecting unit driving unit 23 via the interface unit 22.

When the tack cam is depressed, the knitting machine count meter unit 20 releases the low speed command signal to the control unit 21 of the power motor, and then outputs a medium speed or high speed selection signal to the control unit 21 of the power motor, Set the knitting machine to medium or high speed operation.

Next, when the knitting machine reaches a second preset value which defines how many revolutions of the knitted fabric including the tack are to be knitted down, the knitting machine is again operated at a low speed, the excitation signal to the rotary solenoid S is released, and the cam is released. Return to the original state. When the cam is returned to the original state, the knitting machine count meter section 20 is operated as described above.
, A selection signal of a medium speed or high speed signal is input to the power motor control unit 21 to set the knitting machine to a medium speed or high speed operation.

Next, the position for taking out the knitted fabric (cutting position)
Until the third preset value for lowering the same knitted fabric is reached, the knitting machine stops. A series of operations for adding a knitted fabric including a tack to the knitted fabric end is completed.

If a fourth preset value is set within the first preset value so as to knit the tack structure one by one, after one anti-knitting, the low-speed signal is sent from the knitting machine count meter 20. Is input to the control device (inverter) of the power motor 21 to operate the knitting machine at low speed. On the other hand, the knitting machine count meter unit 20 outputs an excitation signal to the needle selecting unit driving unit 23 via the interface unit 22. The needle selecting means driving means 23 to which the excitation signal is input is
For example, the rotary shaft of the needle selecting means provided in the dial cam device shown in FIGS. 3 and 4 is rotated by the rotary solenoid S, and the tack cam 6 of the dial cam device is pushed down. Tack cam is pushed down, control part 2 of power motor
The low speed command signal to 1 is then released, and then a medium speed or high speed selection signal is output to the control unit of the power motor 21 to set the knitting machine to medium speed or high speed operation.

Next, when the knitting machine including the tack reaches a second preset value which defines the number of rotations of the knitted fabric, the knitting machine is again operated at a low speed, the excitation signal to the rotary solenoid S is released, and the cam is released. To its original state. When the cam is returned to the original state, the knitting machine count meter 2
A selection signal of a medium speed or high speed signal from 0 is input to the control unit 21 of the power motor, and the knitting machine is set to a medium speed or high speed operation. By the above-described operation, a knitted fabric including a tack is added for each counter.

The configuration of the needle selecting means driving means described above is merely an example, and does not limit the present invention. Various changes, improvements, and modifications are possible within the scope of the claims. For example, in the above-described embodiment, the needle selecting means driving means provided in the dial cam device has been described. However, a similar needle selecting means driving means may be provided in the cylinder cam device.

The needle selecting means driving means is not limited to a specific needle selecting means. By providing driving means for all the needle selecting means, the needle selecting means driving means can be arbitrarily operated to perform various knitting. It is also possible to gain land.

[0044]

According to the present invention, a knitting machine count meter section and a needle selecting means driving means interlocked with the knitting machine main body are provided in order to knit a knitted fabric including a tack at the other end of the knitted fabric in an arbitrary needle selecting means. Therefore, it becomes easy to add a knitted fabric including a tack separately from the knitted fabric knitted by each needle selecting means to the knitted fabric end. By this, when knitting a knitted fabric, conventionally, operations such as inserting a spun yarn such as a cotton yarn which is difficult to unravel or replacing a previously knitted yarn with a spun yarn were performed artificially. Could be eliminated. In addition, the artificial work of inserting a color thread that serves as a mark in the case of a knitted fabric that is difficult to unravel conventionally can be eliminated because the knitted fabric portion including the tack can be used as a mark. As a result, labor saving was achieved, so that the workability was further improved, and the production amount of the knitted fabric was significantly improved.
